We recommend you use:
<span class="application">VeraCrypt</span> to share encrypted files across different operating systems.
<span class="application">LUKS</span> to encrypt files for Tails and Linux.
See the [[difference between *file containers* and *partitions*|veracrypt#container-vs-partition]].
*Plausible deniability*: in some cases (for example, with <span class="application">VeraCrypt</span> hidden volumes), it is impossible for an adversary to technically prove the existence of an encrypted volume.
[VeraCrypt: Plausible Deniability](https://www.veracrypt.fr/en/Plausible%20Deniability.html)
Still, [[!wikipedia Deniable_encryption desc="deniable encryption"]] might not protect you if
you are forced to reveal the existence of the encrypted volume. See:
[Security-in-a-Box: Creating a hidden volume](https://securityinabox.org/en/tools/veracrypt/#4-creating-a-hidden-volume)
